ABSTRACT

An athletic shoe (10) having an upper (2) and a sole (14) is disclosed. The sole (14) includes an intermediate sole layer (16) of a resilient cushioning material. A bead (46) is disposed about the perimeter of the shoe in the heel spring section to enhance the heel stability.

Description

~ 1 ~2~37 ATHL~TlC SHOE Wl~H HEEL STABILIZER

TECHNICAL FIELD
The present invention relates to athletic shoes, and in particular, to Q heel stabilizer used with the shoe.
BACKGROUND OF THE INVENTION
Shoes of the prior art have frequently incorporated into the shoe upper heel counters, i.e., a stiffener to give form to a shoe upper around the area of the heel. In athleffc shoes, wherein the shoe is subjected to more vigorous motion than a normal walking shoe, counters have beén subject to premature fatigue. The fatigue can result in loss of rigidity of the counter, splitffng of the counter, or breaking away o~ the counter frosn its juncture to the sole. As the heel cowlter f~tigues, heel stability, i.eO, the capability of the shoe to exert a stabilizing influence on ~e foot in the area of the heel, particularly in the lateral direction, may lessen.
It is believed that the fatigue of heel counters is caused by excessive motion of the rear foot by some runners, and the tendency of some runners to pronate, i.e., to roll the foot inwardly during running.
The problem of heel counter fatigue and the need for heel stability is even more acute with heavier athletes. Furthermore, the problem of heel counter fatigue and the need for greater heel stability increases when relatively thick cushioning intermediate sole layers are incorporated into the athletic shoe. Thick intermediate cushioning sole layers are frequently used in present day running ~nd jogging shoes.

The present invention is directed to ~n athletic shoe. The shoe i~

2 ~ .~ 7 -2-~

, according to one aspect of the invention, includes an upper which has an outer surface and an inner surface. The shoe upper includes a heel spring section and a toe spring section. A sole, including an outer sole layer, is secured to the upper. The outer sole layer has an upper major surface connected to the shoe upper and a lower major surface which faces the ground. An external portion of the upper major surface of the outer sole layer, at least in the heel spring sec~ion, extends beyond the area where the sole is secured to the upper. A bead is secured between the outer surface of the upper and the external portion of the outer sole area. The bead extends around only the heel spring section for enhancing heel stability.
In a preferred embodiment, an intermediate sole layer is interposed between the upper major surface of the outer sole layer and the upper. The intermediate sole layer is formed of a cushioning resilient material having a hardness less than the hardness of the outer sole layer.
The intermediate sole layer also has an external portion of its upper major surface which extends beyond the area of juncture between the shoe upper and the sole. The sole is secured to the upper major surface of the inter mediate layer. The bead is preferably formed of a resil-ient material and is attached to the external portion ofthe intermediate sole layer. The bead is disposed around the entire perimeter of the heel counter and at an area where it is believed the greatest stress is placed - upon the heel counter. That is, adjacent an area where the upper is joined to the intermediate sole area.
By utilizing a heel stabilizer of the present invention, the heel stability of the shoe is enhanced.
By locating the heel stabilizing bead only in the heel spring section of the shoe, the tendency for excessive motion is reduced in this area, while permitting or trans-ferring excessive motion to the toe spring section. The i~2737 ,~
-2a-utilization of a heel stabilizing bead in accordance wi~h the present invention may lessen the tendency of certain runners to pronate, provide additional lateral support, and act as a barrier to excessive lateral forces of the rear foot. The heel stabilizing bead also tends to preserve the heel countersl original shape and strength and, hence, alleviate to a substantial degree the premature fatigue of the counter.
Other aspects of the invention are as follows:

DE?AILED DESCRIPTION OF THE INVENTION
Referring to the drawings in detail, wherein like numerals indicate like elements, there is shown in Fig. 1 an athletic shoe in accordance with the present invention designated generally as lû. The shoe 10 includes an upper 12 and a sole 14 secured below it. The sole 14 is made up of an intermediate sole layer 16 and an outer sole layer 18.
The intermediate sole layer 16 is in turn broken down into a base layer 20 and a heel lift layer 22. The outer sole layer 18 is preferably made of a hard resilient ar.d flexible wear resistant material, such as rubber or other comparable synthetic material. The base and heel lift layer 20, 22 of the intermediate sole layer 16 are made of a cushioning resilient material having a hardness less than that of the outer sole layer 18, and preferably within the range of approximately 35 to 55 durometers on the Shore A scale.
The shoe lû can be divided into various sections in several manners.
One method is to define the sections in accordance with the areas ~ ~ ~27~37 defined around the last upon which a shoe is formed. As seen in Fig.
2, line Ll extends through the shoe 10. The area forward of line Ll is generally referred to RS the toe spring section and the area rearward of line L1 is generally referred to as the heel spring or heel height S section. In relation to the foot, the heel spring section is generally the area behind the ball of the foot. Another manner of dividing the shoe into various sections is seen in Fig. 4. Lines L2, L3, and L4 divide the sole 14 and shoe 10 into four sections which relate to four areas of the foot. The area forward of line L2 can be referred to as 10 the toe section. The area between lines L2 and L3 can be referred to as the forefoot section, and the area between lines L3 and L4 can be referred to as the arch section. The area rearward of line L~ can be referred to as the heel section.
As seen in Figs. 1 and 2, the outer surface of upper 12 is formed of a plurality of sections of material 24, 26, 28, 30, 32, 34, 36 and 38 sewn together as indicated by dashed lines. The location, configuration and number of the various sections of material 24-38 can be varied for structural and design reasons. The various sections of material 24-38 can be made of the same or varying materials, again for either functional 20 or design purposes. As illustrated, sections of material 26-34 are formed of a first material, such as leather, and sections of material 36, 38 are made of a second synthetic material.
In addition to being segmented, the upper 12 is made up of a plurality of layers. As seen in Figs. 3 and 5, the section of material 25 34 is attached, preferably by an adhesive, to the upper surface of heel lift layer 22. One or more internal layers of material, such as layers 40, 42, are secured to the outer layer of material of upper 12. The internal layers 40, 42 are attached to adjacent parts of the upper 12 in a suitable fashion. For example, layer 40 is attached to the section 3~ of material 34 by the sewn lines shown in Figs. 1 and 2, and to the heel lift layer 22 by an adhesive. The layer 42 is attached to an upper surface of the layer 40 by an adhesive.
A heel counter 44 is disposed between the section of material 34 and the internul layer 4U. The heel counter 44 is made of a 35 relatively stiff material to provide form and stability of the upper 12 ~ ~ 6~737 in the area surrounding the heel. The heel counter 44 is received svithin and extends completely throughout the section of material 34. The heel counter 44 extends from an inside edge of the upper 12 adjacent the rear of the arch section, around the inside edge and around the back 5 of the heel section to the outside edge of the upper 12. On the outside edge of the upper 12, the counter 44 also extends generally to the area adjacent the rear of the arch section. In vertical height, the counter 44 extends upward from the heel lift layer 22 to approximately two-thirds the height of the upper 12. The eounter 44 gradually increases 10 in height proceeding in a rearward direction. It should be understood that heel counters of other size and shape are contemplated by the present invention, so long as they perform the convention~l function of a heel counter.
As was discussed above, heel counters in athletic shoes are 15 frequently subject to premature fatigue. To alleviate this problem and to enhance the heel stability, a bead 46 is attached to an upper surface of the intermediate sole layer 16. A porffon of heel layer 22 extends external of the area where the sections of material 30, 32 and 34 of upper 12 are joined to it. The heel lift layer 22 thus has an external 20 major surface disposed outside the outer surface of the upper 12. This external major surface extends around the perimeter of the upper 12 in the heel and arch sections. The bead 46 is attached to this external major surface. The forwardmost portions of the bead 46 are attached to similar external major surfaces of base layer 20. The bead 46 25 extends along the perimeter of the shoe 10 along its inside, outside and rear edges of the heel spring section. The bead 46 promotes heel stability and preserves the heel counter's original shape and strength.
By locating the bead 46 adjacent the area where the upper 12 joins the intermediate layer 16, the bead 46 is disposed oy the area where stress 30 concentrates on the counter 44 and provides support for the counter at this stress area. The bead 46 also acts as fl barrîer to excessive lateral forces of the rear foot.
The bead 46 has a flat bottom surface which is adhesively attached to the exterIlal major s~u~faces of heel lift layer 22 and base layer 20.
35 The bead 46 has an outer curved surface and a upper surface which ~ 3 ~73~

slopes downwarclly and inwardly from the outer surface. The bead 44 thus takes on a wedge-shaped configuration with the inwardly sloping surface fitting generally under an outer surface of the shoe upper 12.
The inwardly sloping surface is disposed at a particular angle to 5 accommodate a particular shoe upper. As seen in ~igs. 3 and 5, with reference to lines L5 and L6, ~he inwardly sloping surface is angled at approximately 30 above the horizontal. This slope can vary from approximately 30 to approximately 60 above the horizontal. A slope approximately 60 in the slternate bead 46T is shown in Fig. 6. Also, 10 as seen in ~igs. 5 and 6, the inwardly sloping surfaces of the beads 46, 46' are curved and the angle of the slope is an approximation taken as a tangent from approximately the center of the curved inwardly sloping surface. The particular angle of the slope is determined by the parffcular upper with which the bead is used. A bead with a width of 15 approximately one-half inch and a thickness of one-quarter inch has been found suitable.
The bead 46 is preferably shaped from a strip of resilient material, such as foam rubber, ethylene vinyl chloride, (EV~), or extruded plastic.
The bead 46 preferably has a hardness between 30 and 75 durometers 20 on the Shore A scale with a range of 35 to 45 durometers on the Shore A scale found to be especially suitable.
~ n the embodiment shown, heel lift layer 22 is shown disposed above base layer 20. It should be understood that the disposition of these layers could be reversed wherein a major portion of the bead 46 25 would be attached to a base layer. An intermediate sole layer 16 with a thickness of approximately one inch in the heel section has been found suitable in one embodiment of the invention.
Numerous characteristics and advantages of the invention have been set forth in the foregoing description, together with details of the 30 ~tructure and f~ction of the invention, and the novel features thereof are pointed out in the appended claims. The disclosure, however, is illustrative only, and changes may be made in detail, especially in matters of shape, size and arrangerllent of parts, within the principle of the invention, to the full extent indicated by the broad general 35 meaning of the terms ~n whicll the appended claims are expressed.
